It's good to go!

sounds like it could be a loose spark plug. Get in there and torque them down. If you have a torque wrench the spec is
Spark Plug to Cylinder Head . . . . . 30 Nm (22 ft-lb) (Bentley, page 020-11)
If you need to replace them they are Bosche F7 L DCRs (Bentley, page 020-11)

Also make sure the coil boots are in good shape and not damaged

OP has confirmed to me via text message that he will tackle this in the AM and post his results.

I'm confident this is the fix.

This was not it.
Mechanic believes lifters are ticking and needs oil change and vaccuum leak.

Maybe the oil pump is actually faulty and its not lubricating the top end properly...

The mechanic(Ferman Mechanic for 18 years) who looked at it, said my oil NEEDED to be changed.
Said the car was drivable, he stated it was a tick not a knock.

So he's going to do it tonight, and after the car has been sitting for a year, says it'll probably clear up, and he believes the oil pump is fine, but I may just have it changed anyways.

Can't remember. Does your engine have vanos? My E36 vanos knocked for a short while after it had been sitting for 6 months.

You're correct in that they came with only 4 and 6 cylinder engines. But, one of the 8 cylinder engines (M62 per Joe) came with vanos.

I could not remember which V8 had it. If OP's did, it could be a possible cause of the noise. I related it to my E36 because, when it was down for 6 months or so, the vanos made a very similar noise for a short time after the first start up.

Well you can just go add it back on the list. Alpina made five E36 with the M60 engine.
Alpina B8 4.0
